N2 - Due to the difficulty of healing chronic wound, in the process of changing dressing, secondary damage on the tissue caused by adhesion should be prevented. In this study, the new dressing of particle hydrogels synthesized with poly-methyl methacrylate and poly-vinyl alcohol precursors were proposed. In addition, cell safety tests, animal's allergic stimulation, and animal's wound healing experiments were conducted for particle hydrogels. On one hand, in L929 cell experiment, the results of particle hydrogels extract 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide tests and lactate dehydrogenase test trial show that there are no safety concerns over particle hydrogels. On the other hand, New Zealand white rabbits were chosen for skin sensitization tests in animal trials, which show the consistent results. At last, wound healing tests used diabetes induction with 10-week-old rats and three-month-old Landrace pigs, with the tissue histology. In short, through this experiment, it is found that in the early phase of the diabetic rats and pigs' wound healing, using particle hydrogels can enhance collagen formation, and achieve the goal of faster wound healing.
